摘要
研究了山西省4座典型焦炉周边环境空气中总悬浮颗粒物(TSP)碳组分特征,分析了不同装煤方式和炭化室高度对其的影响。结果表明:(1)焦炉周边环境空气中TSP质量浓度为711.95~2938.41μg/m^3,其中有机碳(OC)、元素碳(EC)的质量浓度分别为189.45~595.90、285.38~806.71μg/m^3,总碳占TSP的质量分数为44.81%~67.45%;捣固焦炉周边的TSP及其碳组分浓度高于顶装焦炉,炭化室高度越高的焦炉周边环境空气中TSP及其碳组分浓度越低。(2)4座焦炉周边环境空气TSP中OC和EC质量比为0.66~1.04,说明焦炉周边环境空气中碳组分以一次污染为主。(3)4座焦炉周边环境空气TSP中碳组分的分歧系数为0.092~0.490,均小于0.5,总体来说装煤方式和炭化室高度都对焦炉周边环境空气TSP中碳组分的分布有一定影响,特别是装煤方式和炭化室高度都不同的焦炉周边环境空气TSP中碳组分差异较大。
Carbon components characteristics of total suspended particulate(TSP)in ambient air around 4 typical coke ovens in Shanxi Province were studied,and effects of loading patterns and carbonization chamber heights were analyzed.The research showed:(1)the TSP mass concentrations around the coke ovens were 711.95-2938.41μg/m^3,in which the organic carbon(OC)and elemental carbon(EC)mass concentrations were 189.45-595.90 and 285.38-806.71μg/m^3,with the mass ratio of total carbon to TSP 44.81%-67.45%.Carbon components concentrations were higher around tamping coke ovens than top mounting ones,and those were lower around coke ovens with higher carbonization chamber heights.(2)The OC/EC(mass ratio)ranged from 0.66 to 1.04,indicating that carbon components around 4 coke ovens were mainly primarily originated.(3)The coefficients of divergence were 0.092-0.490(below 0.5).In general,loading patterns and carbonization chamber heights had certain effects on carbon components distribution,especially for the coke ovens with different loading patterns and differet carbonization chamber heights simultaneously.
